We were just talking about this earlier today. Windows 8.1 is set to roll out to current Windows 8 users on October 17th, with general availability on October 18th, however, Microsoft will also be rolling out a GA Rollup A update for the operating system.

Even though Windows 8.1 has reached RTM and is nearing its general availability, Microsoft will also be releasing a “GA Rollup A” update upon the release of the operating system. Call it an update for the update, if you will. This update will finalize the Windows 8.1 code, since technically Windows 8.1 isn’t finished yet even though it hit RTM. You can read more about this update here.

Now, it appears that this update has leaked onto the internet. The x64 variant of this update has leaked and weighs in at about 232MB. No word on the a 32bit update just yet. The package contains three patches, labeled KB2894179, KB2883200, and KB2894029.

We wont post download links, however, you can head over to the VIA link below to do a little ‘investigation’ of your own to find the download. Microsoft is set to roll out this update via Windows Update soon.

The leak was spotted by FaiKee and posted on his Twitter account. The update package consists of three patches, according to the report; KB2894179, KB2883200, and KB2894029. As we always do in these situations, we will not be providing any direct links to the leaked files.

The previous reports on GA Rollup A stated that the total download size was about 200 MB for the x64 version. There’s been no indication of a leak for the x86 or Windows RT versions, but their download size is expected to be even smaller -about 100 MB.

Of course, everyone with Windows 8 installed on their PC could simply wait until Microsoft pulls the trigger on the official update to Windows 8.1 in the Windows Store. In the US time zones, that is expect to happen in the morning hours of October 17th, for everyone else, a day later.

Update: This update also appears to remove the “Secure Boot not configured” watermark, even if Secure Boot isn’t configured.
